IP to Hostname Aliasing

The IP-to-Hostname Aliasing function accesses the Domain Name System (DNS) server to define hostname aliases for client and server IP addresses.

There are two separate sets of IP addresses: one for clients, and one for servers. When IP-to-Hostname Aliasing is enabled, alias names will replace IP addresses within Guardium® where appropriate.

  1. Click Protect > Database Intrusion Detection > IP-to-Hostname Aliasing to open IP-to-Hostname Aliasing.
  2. Mark the check box for Generate Hostname Aliases for Client and Server IPs (when available) to enable hostname aliasing.

    A second check box can now be accessed. The name of this check box is Update existing Hostname Aliases if rediscovered.

  3. Mark the check box to update a previously defined alias that does not match the current DNS hostname (usually indicating that the hostname for that IP address has changed). You may not want to do this if you have assigned some aliases manually. For example, assume that the DNS hostname for a given IP address is dbserver204.guardium.com, but that server is commonly known as the QA Sybase Server. If QA Sybase Server has been defined manually as an alias for that IP address, and the check box for Update existing Hostname Aliases if rediscovered is marked, that alias will be overwritten by the DNS hostname.
  4. Click Apply to save the IP-to-Hostname Aliasing configuration.
  5. Do one of the following:
    • Click Run Once Now to generate the aliases immediately.
    • Click Define Schedule to define a schedule for running this task. See Scheduling for more information.

To view the aliases defined, see Aliases.
